The biomimetic synthesis of guaianolide dimers lavandiolides H, I, and K and artematrolide F containing a spirolactone moiety has been accomplished for the first time from naturally abundant arglabin in four to six steps with an overall yield up to 60%, and a series of natural product-like guaianolide dimers, trimer, and tetramer were also successfully synthesized. Notably, the trimeric compound exhibited
首次从天然丰富的阿甘油四到六步完成了愈创木酚内酯二聚体lavandiolides H、I和K和含有螺内酯部分的蒿内酯F的仿生合成,总收率高达60%,以及一系列天然还成功合成了类产品愈创木酚内酯二聚体、三聚体和四聚体。值得注意的是,三聚体化合物表现出比索拉非尼更有效的抗肝癌细胞毒性,IC 50值为 6.2 μM (HepG2)、6.8 μM (Huh7) 和 7.2 μM (SK-HEP-1)。
